MAM, IS DOUBLE DISPACEMENT REACTION UNDER DISPLACEMENT REACTION?

Dear Student,

Displacement reaction may be defined as a reaction in which highly active species displace less active species from it's compounds. It is of two types-

Single displacement: This is when one element trades places with another element in a compound. These reactions come in the general form of:

A + BC → AC + B

One example of a single displacement reaction is when magnesium replaces hydrogen in water to make magnesium hydroxide and hydrogen gas:

Mg + 2 H2O → Mg(OH)2 + H2

Double displacement: This is when the anions and cations of two different molecules switch places, forming two entirely different compounds. These reactions are in the general form:

AB + CD → AD + CB

One example of a double displacement reaction is the reaction of lead (II) nitrate with potassium iodide to form lead (II) iodide and potassium nitrate:

Pb(NO3)2 + 2 KI → PbI2 + 2 KNO3

Hence, Single & Double Displacement Reactions comes under the same category i.e. Displacement Reactions.

Dear student.
Yes, A double displacement reaction is a type of reaction in which two reactants exchange ions to form two new compounds. Its a type of displacement reaction
